Answer:

sold 120 chocolate bars

sold 140 peanut butter bars

Step-by-step explanation:

x = peanut butter bars

y = chocolate bars

x + y = 260, total lbs

0.25x + 0.30y = 71, money

solve double variable equation

multiply -4 on both sides for 2nd equation

-x + -1.2y = -284

add both equations together

-0.2y = -24

y = 120

x = 260 - 120

x = 140

sold 120 chocolate bars

sold 140 peanut butter bars

Answer:

The probability that a worker makes between $400 and $450 is .3413 using the calculator and .34 using the empirical rule.

Step-by-step explanation:

There are two ways to approach this problem.

The first way is to find the z-score corresponding to $400 and $450 weekly wage and find the p-value in between these values.

If you use the normalcdf function on your calculator and put 0 and 1 as the lower and upper bounds, respectively, you will get an area of .3413.

Another way of looking at this problem is to recognize that the weekly wages given are the mean and one standard deviation above the mean.

We can use the Empirical Rule, 68-95-99.7, in order to see that going one standard deviation above the mean would be an area of 68/2 = .34.

I've attached an image that shows you what the normal curve looks like.

Answer: Choice C

Vertex = (5, -2)

===============================================

Explanation:

Vertex form is [tex]y = a(x-h)^2 + k[/tex] where the vertex itself is located at (h,k)

As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.

In the case of choice C, we have [tex]y= \frac{1}{2}(x-5)^2 - 2[/tex] which is the same as [tex]y = \frac{1}{2}(x-5)^2 + (-2)[/tex] and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)

Step-by-step explanation:

The natural log has a base of 'e'. That is the definition of the natural log. Therefore, using logarithm rules, 'e' to the power of the right side equals 'y':

[tex] {e}^{ {2}^{x} + 1 } = y[/tex]

Answer:

Step-by-step explanation:

In this problem, x is the exponent as the term '2' is multiplied by itself x times. If you look a bit further, you will see there is also an invisible power on 1, but 1 raised to any exponent will be 1 itself so it isn't considered.

Answer:

t = 11 years

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 9/100

r = 0.09 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(14,382.05/5,403.00) / ( 4 × [ln(1 + 0.09/4)] )

t = ln(14,382.05/5,403.00) / ( 4 × [ln(1 + 0.0225)] )

t = 11 years

Summary:

The time required to get a total amount of $14,382.05 with compoundeded interest on a principal of $5,403.00 at an interest rate of 9% per year and compounded 4 times per year is 11 years.

Answer:

(-4,-2)

Step-by-step explanation:

This is because in order to reflect over the x-axis, the x-axis stays the same and the y-value is the exact opposite of the original y-axis.

(x, y) = (x, -y) in other words.

This is as simple as I can put it, hope this helps :)

Please tell me if you need more help.

Answer: (-4,-2)

Step-by-step explanation:

the rule for reflecting over the x axis is

(x,y) = (x,-y)

(-4,2) = (-4, -2)

Answer:

I had two other people with the same question, so I'm gonna assume that the radius is 2 and the height is 8. Here is the answer: 39.5 in^3

Step-by-step explanation:

The formula for a cone is (pi)(r^2)(h/3)

Since we have to use 3.14 for pi, we plug 3.14 in for pi:

(3.14)(r^2)(h/3)

The radius is 2 and the height is 8, so we plug in those numbers:

(3.14)(2^2)(8/3)

Simplify:

(3.14)(4)(2.666...)

Multiply:

(12.56)(2.666...) -> 39.49333...

Finally, we round 39.49333... to the tenths place:

39.5

Hope this helps :)

Answer:

30  and 110 degrees

Step-by-step explanation:

The angles sum to 360 degrees

  you have   60 + 160 = 220    leaving   140 more in a ratio  3:11

     one is   3 / (3+11) = 3/14      3/14 * 140 = 30    the other is 110

Step-by-step explanation:

If the number of the seats are vacant is 8. Then the number of chairs in a row will be 8.

Division means the separation of something into different parts, sharing of something among different people, places, etc.

64 chairs were arranged in equal rows. 56 students came to sit in the chairs. If the same number of students sat in each row. Then the number of the chair in a row will be

Let the number of the row be x. Then we have

[tex]\rm \dfrac{64}{x} = 8\\\\\\x \ \ = 8[/tex]

Then the number of the row is 8.

Hello there.

Do you see those half shaded squares on the top? Those count as half a square.

Do 6 times 3 to get 24. Multiply 24 with 16 to get 384.

There are 6 half shaded squares which equals to 3 full squares. Multiply 3 and 16 to get 48. Lastly, add 384 with 48 to get your answer.

When a line has an undefined slope, it means that it is a vertical line. Vertical lines are written in the following form:

For any vertical line, the x-coordinate is constant. This means that for any point that falls on the line, the x-coordinate will always be the same.

If we're given that the line passes through the point (4,-2), this means that the x-coordinate for every piont this line passes through is 4.

In other words, the x-intercept of this line is 4.

Answer:

Step-by-step explanation:

None of the answers look right to me unless you are given something I'm not aware of.

A(x) can be factored. When it is, the following is what is obtained.

A(x) = (x- 3)(x - 3)

Since the area of a square is

Area = s^2

where s is the length of the side, you can find the square root by using the rules of roots.

s^2 = (x - 3)(x - 3)

√s²= √(x - 3)²

√s² = s

√(x - 3)² = x - 3

Therefore the answer should be s = x-3

The only thing I think you can do is ask whoever is presenting the course how any of those answers are obtained.
